Application filed March 30, 1918. Serial No. 225,624.

To all whom it may concern: Be it known that I, SIDNEY Dar'rnn JACOBSON, acitizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in anAttaching Means for Antiskidding 'Devices, of

which the following is a specification.

This invention relates to an anti-skidding device, and particularly anti-skidding de vices adapted for use upon the wheels of motor driven vehicles, such as automobiles, 'trucks and the like.

One of the objects of the invention is to provide anew and improved anti-skidding device of the chain type, wherein the cross links are readily removable for the purpose of replacement when worn or broken, and so constructed that there is no danger of said cross links to be accidentally detached from the links of the circumferentially disposed chains.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations,

arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claim.

In the accompanying dr( wing, wherein I have illustrated a preferred embodiment of my invention: 7

Figure 1 is a plan view of a portion of an anti-skidding chain, showing my improved cross-link connected therewith.

Figure 2 is a sectional view on line 22 of Figure 1.

Figure 3 is a view in perspective of one form of the device employed to secure the cross-link to the circumferentially disposed chain; and

Figure 4 is a similar view of a modified form of such attaching device.

Referring now to the drawings, wherein similar reference characters refer to similar parts throughout the several views thereof, the reference numerals 1 and 2 denote the circumferentially disposed chains, usually employed in devices of this character, said chains in the present instance being constituted by interlocked wire links, having straight sides as shown. 3 indicates one of the cross chains, the same being extendedbetween the side chains as shown. 4 indicates one of the devices which is adapted to attach one end of the cross chain to the side chain, said device at oneend being provided with an eye 5 formed by. bending the end 6 of the metalcomprising the attaching device about one of the straight sides of a link of the side chain, whereby the attaching member is permanently and movably attached to said l nk.

The opposite end 6 of the attaching device is bent in the form of a hook 7 and is inserted through the end link in the cross chain, as shown in the drawings. Riveted as at 8 to the intermediate portion of the attaching device 4, is a spring member 9, the free end 10 of which normally springs in an outward direction and is received in a depression 11 formed in the end of the hook portion 7, so that the lower end of the spring and the inner surface of the hook are substantially flush.

The rivet 8, which is employed to fasten the spring member 9 to the body of the attaching device, is preferably provided with a squared head which enters a correspondingly formed slot in the spring member, whereby any danger of the displacement of said spring member in a lateral direction is prevented.

In the embodiment of my invention shown in Figure 4, both ends of the attaching member 4 are constructed in a manner similar to that which has already been described, that is to say, both ends of said attaching member are formed into hooks 7, one hook of which is attached to the side chain, and the other to the end of the cross chain. The spring member 9 is attached at its intermediate portion to the intermediate portion of the attaching member 4 by means of a rivet 8, the head of which is squared and which enters a correspondingly formed aperture in the spring member. Each hook is provided with the depression 11 and the free ends 10 of the spring member enter said slot sothat they lie substantially flush with the inner surface of the hooks.

It will accordingly be seen that I have provided a construction well adapted to attain, among others, all the aims and objects above pointed out in a simple and efficient manner. The manner of attaching the cross links to the side chains affords a construction of great strength and yet such that the cross-links may be readily detached, there being no danger of accidental displacement by reason of the disposition of the ends of the spring members and the hook ends of the attaching members. Moreover, the manner of attaching the spring members to the body portion of the attaching members insures against any danger of lateral displacement of the spring during the operation of the device.

Having thus described my invention What I claim as new and desire to secure by Let ters Patent is:

A snap hook comprising a substantially fiat intermediate or body portion, said body portion formed with a hook at one end and the other end thereof being hook-shaped, said hook shaped end being formed. with head adapted to seat in sai a recess, a closure for said. hook shaped end comprising a spring member formed with a rectangulardepression, a rivet connecting said spring member to said body member, said rivet havin a rectangular d depression and thereby preventing lateral displacement of said spring member, the end of said spring member being adapted to seat in said recess. In testimony whereoflafiix my signature in the presence of two Witnesses.
